Change Event Runtime Name of geometry field

[flomickl]

Currently, the runtime name of the geometry event is called geomWKT
which is not a proper name anymore.
Bedder is geometry or geom as a name.
The processors have to be changed in the output strategy.
Also some other fields needs to be added. e.g. relatet epsg fields for new geometry fields

What do you think about this: (before I create a special discussion)
Is it possible to create and use RUNTIME_names that are used more often, like the vocabulary list, globally somewhere?
Instead of define it in each processor class it is stored like Geo.LAT vocabulary in a separate class.

...
private static final String GEOM_RUNTIME="geometry"
private static final String TEMPERATUR_RUNTIME="temperature"
...
        .outputStrategy(
            OutputStrategies.append(
                PrimitivePropertyBuilder
                    .create(Datatypes.String, GEOM_RUNTIME)
                    .domainProperty(Geo.LAT)
                    .build()
            )
...

It is stored in a Class Runtime
and is used like

        .outputStrategy(
            OutputStrategies.append(
                PrimitivePropertyBuilder
...
 ->                   .create(Datatypes.String, RUNTIME.GEOMETRY)
...
                    .build()
            )

The advantage of this approach would be,
that the runtime name e.g. with the keep + updateField method, the correct runtime name can be selected more easily.
